Would greatly depend on condition.
It will be worth nothing If HELLery Clinton gets in as she is all for gun confiscations (IMHO)
100-450 or so
10-1000 USD and up depending on specifics
Depends on the load.
your pre-64 Winchester model 70 Alaskan was made in the first year of production,which was 1960.As to value it is running from 1200 dollars for one in 60% condition,on up to 2,000 dollars for one in 95% condition.
You would have to list the maker,and serial number including any letters before or after to get a answer to your question. Also list the model number.
please list the maker of your rifle to get a correct answer to your question.
The price of your Winchester model 70 in .338Win mag caliber can only be determined if you include the serial number.This will show if you have a pre-64 model 70 Winchester,or a post 64 model 70.Please include the overall condition of your rifle to help determine the value.
See related links below Clarification: 7.62x51mm, .300 Winchester Magnum, and .338 Lapua Magnum are the most popular.
I will start my answer with a question?Are you sure that your winchester model 70 was made by winchester in 1948?I ask this because the 300 win.magnum was not a chambering that was available until the late 1950,s.The cartridge was based on a 458 winchester magnum case that was necked down.The 458 winchester came into being in 1956-1958.It also spawned the 264 win.mag caliber,and the .338 win mag caliber.I would expect that your winchester model 70 rifle was rechambered at some point in time if it is indeed a winchester model 70 made in 1948.This can also be said if we are talking about the .300 weatherby mag chambering.
There is no .338 Lapua Super Magnum. There is a .338 Lapua Magnum which is considered a member of "Super Magnum family". .338 LM uses several different bullet types and drop will depend on bullet type and weight.
